TROLLEY.

SPECIFICATION forming part of Letters Patent N0. 791,835, dated il'une6, 1905.

Application filed November 12, 1904. Serial No. 232,487.

To all whom it may concern.-

Be it known that 1, Louis MoDoNDLE STEELE, a citizen of the UnitedStates, and a resident of Middletown, in the county of Butler and Stateof Ohio, have invented a new and Improved Trolley, of which thefollowing is a full, clear, and exact description.

My invention relates to trolleys or like conducting devices employed inconnection with electric cars, and more particularly to means forpreventing displacement of the contact member thereof from theconductor. Its principal objects are to provide a simple and effectivemechanism of this character.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure 1 is a side elevation of the upper portion of a trolley-pole andthe coacting wire, to the former of which one embodiment of my inventionis applied. Fig. 2 is a top plan view thereof, and Fig. 3 is a verticaltransverse section on the line 3 3 of Fig. 1.

designatesatrolley-pole, at the upper extremity of which is a head orharp 11, carrying a contact member or trolley-wheelf12, which runs uponthe conductor or wire W, supported by hangers H. Surrounding the polejust below the headis a collar 13, from which project opposite pairs oflugs 14 14c,

preferably lying in planes at substantially right angles to that of thewheel. Between these lugs are pivoted arms 16 and 17. The arms extendupwardly toward and outwardly from the conductor, the first of theselying wholly at the front of the wheel, while 17 extends to'a point atthe rear of the wheel. At their upper extremity each of these arms has asubstantially vertical portion 18, from which project bearing members 1919. In openings in these bearing members are rotatably mounted the stems20 of guard members, which are held against downward movement by collars20. fixed upon the portions 18 and contacting with the upper faces ofthe lower bearing members, while they are maintained against upwarddisplacementby nuts 20 threaded upon their lower ends. At the upperextremity of each is an extension 21, projecting from the stem atsubstantially right angles and across the conductor when thetrolleywheel is in coaction therewith. The outer end of the extensionmay be booked at 22. The guard-member extensions are normally held inthis position across the conductor by means of springs 23, convenientlyof spiral form and each having one end attached to the stem and theother 'end to one of the bearing members. The guard members may berotated in their bearings in either direction against the tension ofthese springs, which is exerted to return them to their normal position.

The arms 16 and 17 are drawn toward one another and into contact withsuitable stop projections 24 24, situated upon opposite sides ofthecollar 13, by a spring 24, having an end connected to each of them.Below the lugs the arms depend at 25 and are bent outwardly, beingprovided at their separated ends with eyes 26 to receive the branches 27of the trolley-cord 28.

The relation of the guard members to the 1 wheel is preferably such thatalthough while the bottom of the wheel-groove is in contact with theconductor the arms will be separated therefrom upon the wheels loweringfrom the conductor, so that if there is a tendency to displacement theguard members will contact with the conductor and check this movement,returning the wheel to its proper position. Upon the guard membersencountering any obstructionsuch, for example, as the hangersthey turnupon their stems, and thus are enabled to pass it freely, being returnedto their guard position by the springs when released. It should be notedthat as these guard members are separated from one another, being infront and at the rear of the wheel, they need occupy no greater lateralspace than the trolley-wheel itself, and are thus able to enter anyspace as great as the thickness of the wheel.

When it is desired to remove the trolley from coaction with theconductor, it is only necessary to pull upon the cord in the usualmanner, when, since the tension of the spring ordinarily employed toraise the pole is greaterthan that of the spring 24;, the arms will bedrawn 100 toward one another at their lower ends, thus separating theguard members, when the pole may be drawn down. In a similar manner thetension of the lifting-spring upon the cord separates the guard memberswhen the pole is being raised, permitting the conductor to be receivedbetween the guard members,which guide the wheel-groove into coactiontherewith.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. The combination with a trolley-pole and its contactmember for coaction with a conductor, of a pair of pivoted arms movabletoward and from the conductor, guard members rotatable upon the arms andextending above the conductor, and springs connecting the guard membersand arms.

2. The combination with a trolley-pole and its contact member forcoaction with a conductor, of a pair of pivoted arms movable toward andfrom the conductor, a stem rotatable in each arm, extensions from thestems, and springs connecting the stems and arms.

3. The combination with a trolley-pole and its contact member forcoaction with a conductor, of a pair of pivoted arms movable toward andfrom the conductor, a stem rotatable in each arm, extensions from thestems having hooked ends, and springs connecting the stems and arms.

4: The combination with a trolley-pole and its contact member forcoaction with aconductor, of a pair of pivoted arms movable toward andfrom the conductor, guard members ro tatable upon the arms and extendingabove the conductor, a spring connecting the arms, and a springconnecting each guard member with its arm.

5. A holder for trolleys comprising a collar adapted to surround atrolley-pole, opposite lugs projecting from the collar, arms pivotedupon the lugs, and guard members movable in the arms.

6. A holder for trolleys comprising a collar adapted to surround atrolley-pole, opposite lugs projecting from the collar, arms pivotedupon the lugs and extending outwardly therefrom and also forwardly andrearwardly, and guard members movable in the arms.

7. A holder for trolleys comprising a collar adapted to surround atrolley-pole, opposite lugs projecting from the collar, arms pivotedupon the lugs, and guard members rotatable in the arms and beingprovided with angular extensions.

8. A holder for trolleys comprising a collar adapted to surround atrolley-pole, opposite lugs projecting from the collar, arms pivotedupon the lugs, guard members rotatable in the arms and being providedwith angular extensions, springs connecting the arms, and a springconnecting each guard member with its arm.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
